Using UART at arbitrary BAUD Rate

I am using QSYS on the MAX10. I am interfacing to another board over an LVDS Physical Layer using a UART. The data rate is 80 MHZ. I am planning on oversampling at a clock rate 4x the data rate ie...

I would write a custom UART for this. I seriously doubt any Altera IP would let you run that fast or with 4x oversampling unless you did some major hacking. At that point I think it's easier to start from scratch. Or find a free UART example and modify that.

Thanks.

I was originally going to use the MINIUART from Opencores, but I figured that if Altera already has the IP I might as well use it. It will support a 4x oversample so I just have to map the wishbone to the Avalon-MM. It would be nice o be able to drop in the IP though.
